To all whom it may Applieationhled December a, 1910. Serial No. 590,350.

Be, it known that I, .Hnmmnr EDWIN MILLS, a subject of the King of Great Britsin and Ireland and resident of South Croydon, county 'Surrey, England, have invented. certain new and useful Im rovements in the Oil-Nozzles of Sprayarbureters, of which the followingis a specification. v f

- The object ofmy invention is to produce a device consisting of easily constructed parts which may be speedily assembled and shall not be liable to getout of order.

In carrying the invention 'into effect, I construct the nozzle of three'parts, an outer cover ornozzle, a coupling or union on to which the said outer cever or nozzle screws, and an inner part or jet fittin between the top of the coupling or union-which is covered with gauze) andthe u'n erside of the outer cover or nozzle which is provided with a single orifice countersunk top and bottom; The inner jet, which takes the form of a hollow cylinderclosed at the top, and .which is held stationary, is provided with two passages or orifices in its wall penetrating from the bore of said inner jet to the ex terior thereof and which are arranged at right angles to the lopgitudinal. axis of said inner jet, and at a tangent to the inner surface of the jet so that the fuel is delivered to the space between the-inner jet and outer cover with a swirlingmotion and in a? lane at right angles to said longitudinal axis.- The arrangement is such that the etrol enters the coupling orzunion at the owerend, passes up through the bore of said coupling or'unionand its gauze top, and the l inner jet and out through the before mentioned slanting orskew passages or orifices, the effect of said passages. or orifices being such as to cause the petrol to be broken up and to swirl, circle and twist around the head of the stationary inner jet and inside wall of the outer case from f whicltqit. issues through the orifice "thereof, which is countersunk on top and bottom, still swirling, circling and twisting inafine spray in the form ofa funnel, By this form of const'ruction the ndzzle can be readily taken to pieces, cleaned and put together again, or

q new parts readilysubstituted for damaged or wornones.

- The invention is illustrated by the accompanying sheet of drawings.

Like letters of reference indicate corresponding parts in the several views, I

In the drawings, a-Fig. 1-is the outer case or nozzle, 6 a bevel at the top thereof, 0 milling for pliers grip and a 0 inner and outer countersunk parts of the orifice in the top of said outer case or nozzle and through which. the petrol issues in a funnel-shaped Spray. 71. is a shoulder in said outer case a into which takes-the shoulder h of the inner jet b the bottom part 9' of which rests upon the gauze top ZrFigs. 1 and 3of the coupling or union m which when screwed home therein keeps the inner jet stationary by forcing the shoulder h of said inner jet into contact with the shoulder h of the outer case or nozzle, and p and j are respectively the bores of the coupling or union and of the inner jet. I

The top part f of the inner jet 72. fits stationary within the outer case so as to leave a space i in which swirls, circles and twists the petrol issuing from the two slanting or skew holes g-Figs. 1 and 2-formed in said stationary top part 7 and below the closed top thereof, said holes 9 being arranged so as to extend from the bore of the stationary part to the exterior thereof and in a plane at right angles to the longitudinal axis of the stationary jet to deliver the petrol with a swirling motipn to the space between said stationary jet and the outer case or nozzle.

I findthat a distinct advantage in startin up is obtained if the apparatus is so ad usted in relation to the level of the petrol in the carbureter that the space between the inner and the outer jetis always full of petrol when the engine is standing still and so that there is a small bead of petrol in the outer countersink 0 Having now described my invention, what I claim as new and desire to secure by Letpling to be secured to the carbureter, a

gauze top to said coupling, an outer case or nozzle screwed to said coupling, an inner jet resting on said gauze top, a shoulder on said inner jet to engage with a shouldered porbottom in the head of'said outer case or 10 nozzle substantially as herein described.

In testimony whereof I aflix my signature in presence of two Witnesses.
